Does a Thailand eSIM provide data on a boat?

Do not assume a land-based plan provides offshore service. Save tickets, pickup points and return details before departure.

When does an APAC plan make sense?

Compare it only when the current plan list includes every country in your itinerary; the regional name alone is not a coverage list.

Networks used by Thailand plans

AIS ThailandDTAC Thailand

Networks can vary by plan. Check the plan details before you buy. Where the selected Thailand offer has service, travel data may support navigation, translation and booking messages. Service depends on the chosen plan and local network conditions; offshore and remote areas should be planned with offline information.

Ideas for your trip

Plan your trip to Thailand

Bangkok, Chiang Mai, Chiang Rai

Bangkok's transit network is a city plan; Chiang Mai and Chiang Rai add a separate northern leg. Keep intercity tickets and each hotel address available offline.

Phuket, Krabi, Koh Samui

Phuket and Krabi are on the Andaman coast; Koh Samui is in the Gulf of Thailand. Check the transport leg between coasts and save each transfer's current details.

Railay, Pai, Ayutthaya

Railay, Pai and Ayutthaya each change the shape of a Thailand itinerary; check transfer time and save the return details before leaving your base.

Plan your Thailand itinerary

Choose a Thailand plan for a Thailand-only itinerary. Consider APAC only when its current included-country list covers every stop, and plan island transfers independently from mainland travel.

01
Bangkok food and neighbourhood days
Markets, transit, restaurant research and changing plans create a map-heavy city stay.
Save your hotel address in Thai and English and group visits by area before leaving each day.
02
Chiang Mai city with one day outside town
Temple visits and a countryside excursion call for different meeting points and return details.
Confirm the operator's pickup location and download the route before the excursion.
03
Phuket or Krabi as a single coastal base
A mainland resort stay and nearby boat outing are not the same as travelling across multiple islands.
Keep boat tickets and return arrangements offline; do not rely on mobile data at sea.

Thailand data planning

How much data might your Thailand trip use?

The examples below describe different trip patterns and the assumptions behind each estimate. Your actual use depends on your apps, settings, trip length and access to Wi-Fi.

Seven-day light-use calculator example

3.6–5.5 GB

Assumes: Seven days of messaging, email, browsing and occasional maps, with streaming and video calls off, light social use and few photo uploads. Wi-Fi availability is not included in this activity estimate and may reduce mobile data used.

Seven-day typical-use calculator example

10.1–15.1 GB

Assumes: Seven days with light streaming and video calls, daily maps, moderate social use and photo uploads. Wi-Fi access is not modelled and may reduce mobile data used; hotspot, higher-resolution video and app updates can raise demand.

These are rough planning examples, not plan allowances or promises. Actual data use varies with apps, settings, trip length and Wi-Fi. Compare estimates with the live plan options above.
